Solar grazing has become the default picture of farming under panels. Sheep, a fence, a few thousand modules, a photograph of white dots drifting between the rows. Volkswagen keeps 50 sheep and a guard donkey<\/a> on its Chattanooga array and that image has done a lot of work for the industry. Italy switched on a commercial-scale version in July with no animals on it at all, and a planting list that reads closer to a spice rack than a feedlot.<\/p>\n

Two plants went live in the province of Benevento, in the Campania region. Morcone is rated at 9.8 MWac and Acquafredda at 9.3 MWac, which gives 19.1 megawatts between them. Around 32,500 solar panels stand across the two sites. RWE, the German utility that built and owns them, dated commissioning to July 2<\/a> and puts coverage at roughly 13,000 Italian households.<\/p>\n

Each row rides on a tracker structure about 10 feet (3 meters) off the ground, turning on a movable axis. Italian rules set the minimum height for panels over cultivated land at 6 feet 11 inches (2.1 meters).<\/p>\n

Three feet of clearance separates the two.<\/p>\n

Italy wrote the panel height into its own rulebook<\/h2>\n

Germany leaned on a published specification and a yield threshold, which is how Vattenfall ended up with 146,000 panels and 15,000 hens in T\u00fctzpatz<\/a>. Italy went at it from the geometry instead.<\/p>\n

The Italian agrivoltaic guidelines<\/a>, drawn up by the environment ministry with CREA, ENEA, GSE and RSE, set two minimum heights. Panels over cultivated land have to clear 6 feet 11 inches (2.1 meters), which is the room a tractor and its implements need. Panels over livestock, and fixed vertical modules, have to clear 4 feet 3 inches (1.3 meters), enough for animals to move underneath without ducking.<\/p>\n

Both figures are floors rather than targets. A Bavarian hop grower went to 23 feet on his trellis poles<\/a> because hops climb until they hit something.<\/p>\n

Height buys two things at once. Lifting the modules leaves more of the field workable than a conventional ground-mount does, and the shade underneath cuts incident radiation during the Italian summer, which is when thermal stress and water demand climb. RWE also credits the structures with shielding whatever is growing below from hail, frost and heavy rain. A movable axis means the shade moves through the day instead of parking over the same strip of soil.<\/p>\n

A second Italian number does the heavier lifting. At least 70 percent of the total surface of an advanced agrivoltaic system has to stay in agricultural use. A developer can raise the glass as high as it likes and still fail that test by covering too much ground with it.<\/p>\n

Massachusetts is the closest American rule with figures attached. Dual-use arrays there have to sit 8 feet up on fixed tilt and 10 feet up on trackers, and no square foot of the site may lose more than 50 percent of its direct sunlight. Which puts the Massachusetts tracker minimum at 10 feet against Italy’s 6 feet 11 inches for cropping.<\/p>\n

NEW JERSEY, AUG 17<\/div>\n
52.06 MW<\/div>\n
16 dual-use projects awarded, out of 33 preliminary proposals worth about 140 MW.<\/div>\n<\/div>\n<\/div>\n

The grant only lands if the field keeps working<\/h2>\n

Italy pays for this through its post-pandemic recovery plan, under a line the government calls Sviluppo agrivoltaico. Support arrives in two pieces: a capital grant covering up to 40 percent of eligible costs, and an incentive tariff paid on net electricity fed into the grid. GSE, the state energy services operator<\/a>, runs both.<\/p>\n

The measure has since become a financing program worth 1.099 billion euros, administered directly by GSE. Eligible recipients are agricultural entrepreneurs, groupings of them, or temporary business associations that include at least one farmer. An energy company on its own does not qualify.<\/p>\n

That requirement is the part American programs keep arriving at from the other direction.<\/p>\n

Monitoring is written into the eligibility rules rather than bolted on afterward. To qualify as an advanced system, a plant has to carry instrumentation that tracks continuity of the farming, water savings, recovery of soil fertility, the microclimate under the panels and resilience to climate swings. Miss the requirement and the classification goes, and the money goes with it.<\/p>\n

RWE said in November 2025 that it had taken three more Italian agrivoltaic slots at auction, after winning two in the 2024 round. The company describes the auction terms as a contract-for-difference tariff plus up to 40 percent back on investment.<\/p>\n

A university has three years to weigh what grows<\/h2>\n

RWE has put both Campania sites under a three-year monitoring program with the Department of Agricultural Sciences at the University of Naples Federico II. Measurements run before and after installation.<\/p>\n

The Naples team is measuring considerably more than a photo op requires. Agrometeorological readings come first. Soil work covers chemical and biological fertility, and it reaches down to enzymatic activity, microbial diversity and mesofauna, the tier of soil life sitting between microbes and earthworms. Crop measurements cover ecophysiological status and actual yield. Pollinator communities and spontaneous vegetation close out the list, and RWE files the whole exercise under a corporate target of net positive biodiversity impact by 2030.<\/p>\n

New Jersey picked its first 16 farms on August 17<\/h2>\n

The New Jersey Board of Public Utilities voted on August 17 to award 16 projects totaling 52.06 megawatts<\/a>, the first solicitation under its Dual-Use Pilot Agrivoltaics program. The farms sit in Atlantic, Cumberland, Gloucester, Hunterdon, Mercer, Monmouth, Salem and Warren counties. Crops run to soybeans, hay, grains, vegetables, fruit and specialty crops, with livestock in the mix as well.<\/p>\n

The pilot came out of New Jersey’s Dual-Use Solar Energy Act of 2021 and can run to 200 MW over three years, with individual projects generally capped at 10 MW. Land has to be unpreserved farmland already in active agricultural or horticultural production. Each bidding team has to include a landowner, a farmer and a solar operator, and the farmer has to take part in planning and operation.<\/p>\n

Demand outran the award. NJBPU said its first solicitation drew 33 preliminary proposals worth roughly 140 MW, and 52.06 MW of that got through.<\/p>\n

New Jersey Secretary of Agriculture Ed Wengryn called the pilot “the best real-life laboratory to learn the challenges the two industries face.”<\/p>\n

Fifty-two megawatts sounds small against the national picture, and it is not. The National Renewable Energy Laboratory had counted 596 agrivoltaic sites across 65,699 acres and 10,473 MW in the United States as of early 2025, but most of that total is pollinator habitat and sheep grazing. Growing a row crop under a tracker that a combine has to get through is a different job, and there is far less of it.<\/p>\n

Italy runs 19.1 megawatts under a single owner on two sites, with a state grant tied to a farming test written into the design rules. New Jersey spreads 52.06 megawatts across 16 farms, with a farmer written into every bid.<\/p>\n

The rosemary has not been weighed yet<\/h2>\n

RWE’s own release puts the crops in the future tense. The two plants are described as intended for alfalfa, oats, broad beans, rosemary, chamomile and other medicinal herbs, with local farmers choosing, planting and harvesting in consultation with the landowners. No yield figures have been published from either site.<\/p>\n

The sheep belong to the next batch. RWE is building four more plants: Acquafredda 2 at 11.7 MWac in Campania, Cave at 9 MWac in Calabria, and Enna at 9.5 MWac and Carcitella at 8 MWac in Sicily. That comes to 38.2 megawatts and around 50,000 additional panels, scheduled for commissioning in 2026. Grazing is planned under those four.<\/p>\n

American programs already ask for the receipt. Massachusetts requires annual reports on crop or herd productivity from qualifying dual-use projects, and a project that stops filing them can lose its adder for one or more years.<\/p>\n

GSE said it would sign concession agreements with each beneficiary by June 30, 2026, and each plant then has 24 months from that notice to enter service. New Jersey’s pilot has room for 200 MW over three years, and the 52.06 MW cleared on August 17 accounts for about a quarter of it.<\/p>\n","protected":false},"excerpt":{"rendered":"
